Can it be working? I have crashes after running anyone games and tests in 3DMark (besides Time Spy).
I have Asus R7 265 with memory by Elpida and HIS with memory by Samsung. Can it be cause of problems?
Now I tested GTA V, Hitman Absolution, Dayz (that's runs, but second video card not work), Valley Benchmark, Haven Benchmark, 3DMark...
Heart of Iron III is working. I see label "CrossFire" on top right corner.
